This invention relates to a scraper .of the type commonly used inscraping glass to remove paint, varnish or other material which' may bedeposited thereon. It is a A primary object and purpose of the presentinvention to construct a scraper of the type noted in a simple and novelmannerwhereby bolts, screws or the like for fastening the parts togetherare eliminated and the scraper member, which consists of a blade similarto a safety razor blade, may be clamped in place, a scraper beingprovided which'comprises two parts only in addition to the blade usedand which is capable of sustaining the usage toV which a device of thischaracter is put in service. f'

An understanding of the invention may be had from the followingdescription taken i11- connection with the accompanying drawing, 2o inwhich,

Fig. 1 is a perspective view of the scraper of my invention.

Fig. 2 is a perspective view showing the method of assembly ordisassembly of' the which is narrowed to make' a narrow conscraper..

' Fig. 3 isa longitudinal vertical section through the scraper inpartially disassembled relation.

Fig. 4l is a similary lview showing. the

scraper completely assembled.

Fig. 5 is a fragmentary side elevation illustrating the scraper inpartially assembled form, and

Fig.- 6 is a similar view showing the scraper fully assembled.

Likel reference characters refer to like parts in the different figuresvof the draw- 1ng. n

In the construction of the scraper a member of sheet metal is providedof channel form having a web bottom 1 from which'two iianges 2 extendupwardly at opposite sides as shown in Fig. 2. At one end of this membera handle section 3 of inverted channel form is attached partiallycovering the first channel member. In practicethe two parts are madeintegral and formed lby suitable dies and tools into the shape shown.The web or bottom 1 directly in front of the handle section 3 has a slot4 cut therein which is disposed lengthwise of the dev1ce.

The opposite end of the channel memf ber is widened and formed into abase plate 5 from which. at two spaced apart points projections 6 ofcircular outline are pressed upwardly. At each edge of the plate 5 lips7 are formed and are turned backwardly over the plate to provideclamping clips for a purpose which will later appear. A scraper blade,which may be either a blade such as is used with safety razors or one ofasimilar though heavier construction, may

a clamping plate 12, the width being such that iti'may be received underthe clamping clipsv 7. At the oppositeend of the second member the metalis turned downwardly at right angles making an end section 13,

necting section 14, and then terminates in a widerhead 15. i

.With the blade 8 laid upon base plate 5 the section 15 may be passedthrough the slot 4 by turning the second member of the vdevice at anangle to the first member, as

shown in Fig. 2. The narrow connecting f section 14is slightly less inwidth than the width of the slot 4 so that the second mem- .ber ofthedeviceY may be turned back to lie ldirectly over the first memberdescribed. -Vhen thus positioned, as 'shown in Fig.l 3,

the turned down end member comprised of sections 13, 14 and 15 islocated at the front 'end of the slot 4 and the upper member of theIdevice may' then be lowered to substantially the position shown in Fig.5, whereupon the rear edges of the clamping plate 12 will come directlyin frontof the clamping clips 7. Then by pressing against Vthe section15 so as to move the second memand against any disengagement from theprojections 6, as is evident.

The disassembly of the construction is merely a reversal of theoperations described consisting in the movement ot the upper member ofthe device longitudinally, which .movement may be eil'ected by pressureagainst the rear side of the section 15 so as to move the narrowconnecting section 111 lengthwise of the slot 4. This trees the clampingplate 12 of the clamping clips 7 so that it may be lifted to theposition shown in Fig'. 3 and the blade 8 removed for sharpening orreplacement.-

, The construction described is very simple but practical. Theelimination of screws or other securing devices is a very desirablefeature of the present invention reducing the number of parts andeliminating considerable time and trouble in assembling. The deviceconsists of but two parts for holding the blade.

It will be noted that the handle portion 1 of the device is indentedtransversely as indicated at 16 between the ends of the slot 4. This isfor the purpose that on moving the other handle portion 11 with theintegral elamping plate 12 longitudinally or to the position shown indotted lines in Fig. 4L, the inner edges of the part 15 will engage withthe indentatiens at 16 holding the device in the position shown indotted lines in Fig. 4. The edge of the blade 8 will be covered by theclamping plate 12 and a guard thus made so that there is no danger ofcutting by the blade when the device is not used or when it is carriedin the pocket of aworkman. It is also evident that the movement of theclamping plate 12 from the position which it occupies when the edge ofthe blade is exposed, as in Fig. 1, to the dotted line position shown inFig. 4, removes any material which has collected on the blade ahead ofthe edge of the clamping plate 12 thereby scraping and cleaning the samefrom the blade.

These are features ot advantage. Paint or putty which adheres to theblade is very quickly and easily removed in this manner.

The construction has proved verypractical and serviceable. The inventionis deiined in the appended claims and is to be considered comprehensiveoi all forms ot structure coming within `their scope.

I claim:

1. A scraper comprising, one member having a handle portion of channelcross section with a slot cut through the webof said `handle portion,said handle portion at one end being widened to form a base plate,

spaced apart lugs projecting v'from said base plate, a blade locatedagainst the base plate lhaving openings into which said lugs eX- tend, asecond member having a handle portion'also of channel form invertedlwith respect to the handle portion of the first member and at one end-being widened soas to lie over said blade and base plate, Vand at theopposite end being formed with an inturned locking member adapted topass through the slot in the web of the iirst handle portion, saidlocking member being slidable lengthwise of said slot, and clampingmeans on one oit said plates with which the other engages onlongitudinal sliding movement of the Imembers relative to each otherthereby clamping` the blade between said plates. Y Y

2. A construction comprising the elements in combination defined inclaim 1, said locking member comprising a section wider than said slotwhere said section joins the handle portion to which it is attached, asecond section slightly narrower than said slot and a third terminalsection wider than the slot, the length of 'the second and narrowestsection being slightly greater than the thickness of the Vmetal fromwhich the first member is made. v

3. A device oi' the class described comprising, two contiguouslyarranged members having superimposed clamping portions, said membersbeing movable relative to each other, interengaging means on saidmembers near their clamping portions, said means serving wheninterengaged to retain the clamping portions together and beingdisengageable by relative sliding movement of the members, and meansassociatedv with both members remote from the clamping portions servingas a combined sliding and hinge connection between said members.
